英文摘要	a highly active and selective k-pd/mnox-zro2-zno catalyst for the one-step synthesis of 2-pentanone from ethanol is described. the possible reaction pathways for ethanol reaction over k-pd/mnox-zro2-zno catalyst were investigated by means of tpsr, co2- and nh3-tpd techniques. the reactions were performed in a fixed bed continuous flow reactor. complete conversion with high selectivity for 2-pentanone, was observed under 370 similar to 390degreesc, 2 similar to 4 mpa, ghsv = 8000 similar to 10,000 h(-1) and lhsv < 1.25 h(-1) conditions. ethanol reactions over k-pd/mnox-zro2-zno catalyst showed that the catalyst could catalyze dehydrogenation. aldol. dehydration and hydrogenation reactions. both acidic and basic properties are found on the surface of k-pd/mnox-zro2-zno catalyst, whose multifunctionality with the combination of basic, acid and metal sites may be responsible for the efficiency of the k-pdmnox-zro2-zno catalyst.
